Well, the digital versions were not money-makers on their own anyway... they were just one additional facet of D&D Insider, which included the 4E Character Builder, Monster Builder and a couple other things. So WotC earnings from it (or lack thereof) were based on 4E's popularity in and of itself.I think they were still profitable when WotC cut the print version...bit on a downward trend, and the digital version did not turn it around.
